This invention relates to sprinklers, and morefparticularly to lawn sprinklers, and irrigation sprinklers.` s

The general object of the invention is to provide a simple, eiicient and inexpensive lawn sprinkler which willcompletely sprinkle a lawnof predetermined area.

i A more particular object is to provide a lawn sprinkler which will effectively sprinkle the corners of a lawn.

Another object is to provide an oscillative lawn sprinkler which maybe operated by domestic low water pressure to sprinkle a lawn of relatively wide area. i

VA further` object is to provide a lawn sprinkler with an oscillating nozzle constructed without packed joints. s

Other objects and advantages will appear hereinafter. i Y

The invention is illustrated in the annexed drawing which forms a part ofthis specification and in which,

Corresponding parts are designated by th same reference characters in all the figures.

, My sprinklerv includes a casing 1, a water wheel 2, a` water wheel shaft 3, a worm` 4u on said shaft, a worm gear 5 in mesh with said worm, an outlet pipel 6, a link? connecting said worm wheel and the inner end of said outlet pipe, a nozzle 8 connected tothe outer end of said outlet pipe, and aflexible sleeve 9 surrounding lsaid outlet pipe outside the casing 1 and connected at one end to saidtio casing overan outlet 10 in the upper wall of said casing and connected at its other end to said outlet pipe. A base member 1a is secured in the lower part of the casing 1` which member rests upon the lawn and supports the Icasing in an uprightposition;V

One end of the casing 1 is provided with an opening 11 which is closed by a'disc 12 which fits over said opening and said end of the casing andis detachably held inposition on said end by a cap 13, vsaid-'cap being screw seated on said end of the casing by means of interengaging threads 14 and 15 respectively on said end of thef'casing and vin the fiange 16 of said cap. The disc 12 is ormed'in its outer side with awater pocket 17, thev inner wall 18 of which extends upwardlyandinwardly at an angle and is provided with `a central bearing 19 in which the upper @Dd of the shaft 3 is journaled, and

with a plurality of outlet` ports 20 spaced around said bearing for admitting water from said pocket to the blades 21 of the water Vwheel 2. The ports 20 extend at an angle to the rear pocket wall 18 so that the water passing therethrough will impinge direct-ly upon the blades 21 of the water wheel 2 to rotate the said wheel together with the shaft 3 and worm 4, the water wheel being so constructed with a disc 22 which is secured againstthe rear edges of the blades 21, thus confining the water in the wheel between said disc and the pocket wall 18, so that the water must travel outwardly over the Ablades 85 over the outer ends thereof'to escape from the wheel, whereby the maximum power of the'water is utilized to rotate the wheel. The inner and lower endfof the shaft 3 is journaled inia bearing`23` in the inner end 90 of the casing l below the worm wheel 5. The cap 13 is formed with a threaded hose conneetion 24 and with aninlet port 25 leading from said hose connection into the water pocket 17.

The worm wheel is secured on a shaft 26 journaled in bearings 27 and 28 in the easing l, the bearing 28 being' screw seated in one side wall of the casing 1 so that it may be removed to place the worm wheel 5 within or to remove said wheel from the casing The outlet'jpipe e'gtends(init tlifro'ughiV the outlet "T0 and' pivioted to theasing I in said outlet on a pivot 29.

The water passing over the outer ends of the blades 21 of the water wheel tills the interior of the casing 1, the outlet 10 and the sleeve 9 and passes through said outlet out through the outlet pipe 6 into the nozzle 8 and out of the nozzle through the perforations 31, 32, 33 and 34.
